Fuse for hand grenades

FIELD: fuses for fragmentation hand grenades.

SUBSTANCE: fuse for hand grenades has a bush of the detonation assembly connected inside the grenade body that is connected to the cavity of the fuse outer body, positioned in which is an additional functional assembly of the time fuse, that has a pyrotechnical retarder and a flash igniter, which is positioned in the side seat of the fuse body for initiation of the given flash igniter by means of a trigger pricking-safety mechanism that is positioned in the seat of the fuse body asymmetrically relative to the longitudinal axis of the bush of the detonation assembly of the given fuse. The novelty is in the fact that there is a time controller of the hand grenade blast, which contains a shaped retarder frame rotating in the longitudinal axis of the detonation assembly bush. The frame is made for transmission of the initiating fire impulse from the side flash igniter to some section of the side outer surface of the rotating horizontal semi-ring component that has the respective profile for arrangement of the pyrotechnical component of the retarder on it, and connected to the radial component that is positioned in the radius of the horizontal semi-ring component for further transmission of the initiating fire impulse to the time assembly of the fuse, which initiates the main charge of the hand grenade. Provision is also made for a setting and fixing mechanism of the retarder shaped frame through a preset angle of its turn for determining the angle of setting of the rotating shaped frame of the retarder relative to the side flash igniter according to the digital graduated scale of the time fuse, having an increased time range.
